'To aan wnoM'I MAY Cercami; Y' i i A i A ABe it known that I, -ALoNzo T.Boor, of the city'ot Galesburg, Knox couaty,vand State of Illinois, haveinvented anew and useful Improvement in Window-Sash Stops; and do.hereby declare the following descrip; ltion and accompanying drawingsare sullieienthto onoble'anyperson skilled in the art or science towhich it most rapglyeppertana to malce and use mylsaidin'vention .orimprovements without fnrther'invention'or experiment.

Theinature oi'myinvention and improvement consists in'asixnple and novelmethodof suspending the sash at any?` desired, upon itsbein g raised bythe antpinatic-action of an India-rubber or gatta-porche. 'roller or itsequ'ivxb Ichi, vapplied within an incl-ined or angular-ly vformed -b'oxattached tothe faeeside 'of the s'ash by means of a plate connectingtherewith, and hovingthereon avpeculiar'ly formed leverV for controllingthe said roller-while the sashis being lowered; the said lever notonli-performing this function, but serving the purpose of a fastf einerfor securing the Vsash atvnightor otherwise;

i The construction and operation of the device arefully explained in thedescriptionbelow, and likewise ills' A trlz'ted in the4accompanyingdrawings ity-the following figure,I viz Figure 1 is a.front view' of a window frame and sash therein, showing the applicationofthe device thereto.v

` A represents the window frame, B the sash. The box'jis maigi'ly'aplateconstruetedoi an inclined or angular form, a, and suiciently curvedaround from the angle .thrdoftdyreceive atop plate, which is fastened ithereto, 'and rhode to conform to the angle and"curve of the' plate," fslightly sro-es to ferm a enge thereon onderhandthe durved partot placedwith the angle of the inclination aof" the samey down from the edge of,the plate b, and securedthereto by thel flange above ,mentioned beingsoldered thereon. If deemed desirable the plate and the box connectedtherewith may be east whole. Before' the device as thus constructed isapplied tothe sash, theroller c, (seenin dges of lthe plate a are turnedover dotted lines,) of rubber 4oi' its equivalent, is introduced withinVthe angularly formed boil through the open side. i

The device is then attached to the face sideof the-sash," at or nearthetop, and ilnsh with the edge of the same, by two screws d, havingfinished circular washer plates under their heads; In' close proximityto the angular-'ly formed box is alever, C,one portion of which 'leveris made straight, and the other curved'or made of ahooked form. It isplaced obliquely below theV inclined box', as will be observed in' thetop sash, and secured .on the top ofia circular washer plate, the sameas placed under the screw heads by the screw which screw serves as f a.'pivot for the lever to operate on, as well als-fastening it and theplato 'to the sash. A slot `e is made in the inclined side of the 4boxto allow the introduction of the curved part of the lever through thesaine, soV as to enable the lever to control the roller whilerthe sashis being lowered. In the jamb or head ofthe same are two notehesf, inwhich the straight ends of the levers are inserted to serve thepurposeof fastening the sash whenv desired, (see the same in red lneslivn g.1.) The leveren the lower sash is placed obliqirely above the inclinedbox to enable-it to be used as n fastener,` which could not be donewell, -as will hepppar'ent, in a position below as in the top sash. v

i' Oper-ation..

Thofperson wishing to 1ower' thc upper sash, rst removes the lever'fromits fastening position with one hand, andthen tnxns the curved part ofthe s ame into the inclined boi; 'through the slot, over andren theroller,

and thus holds the roller at tho larger'pait of the angle ofthe inclinedbox, while withV the other-hand he lowers A tho sash, and when reachingthe p oint desired, he lets go-of the lever and sash. i -'lhe sashconsequently, frdm: its own gravity, becoming depressed," producesfriction` to the roller means of the. inclined side of the bog, andthe.side of the jamb or bea'd of the same aetingthereon, which frictionthas produced impels the rollerto,

near the apex or smaller part ofA the anglo of vthe inclined boa, wherethe weight of the sash pressing down .on

it holds it fast. The snsh, by reason of the roller traversing theinclined side' of the box,is forced firmly againstV the opposite sideo'f the jamb, which in connection withthe position of the rollerattained from .the movement thus made, and as abovedescribed, the sashis thereby held and snspended without any possibility of its slipping,so that it' force was even exertedit could not be brought down, the sashbecoming wedged as it were betweenv thnsdes of the jamb by its ownweight acting on the roller. 0n the person raising the sash, the rollerdrops me. The boxtlrus far soV formed isV 2 emo to its original positonin the boxl.' The sash is then ready agi te be lQxvei-e on 'themanp'ulation' of the lever en the roller, as above alluded to. The sameoperation attends vche raising and werling ofthe lewer sash.`

Having thus fully described my invention, what I claim therein asvnew,midjesixeV to secure by Letters Patent, isv l n." l The curved lever C,as constructed :1v-nd "arrnged t'o operatie on theV pivotal, ,inlcombix1'x a.ftit l1 ivfrhkthe righte" angled box a, (foi the control ofthe roller therein and its combiuatnwth the notches f to serve asfesteper; substantially in the manner as herein described. l l
